【摘要】 研究了嵌入式数字信号处理器进行代码产生时的指令选择问题,研究复杂指令如何影响寻求最优的树覆盖,同时介绍一个两遍指令选择模型,这种选择模型能够很好的开发和利用可用的指令级并行性.这种技术和以前的工作相比能显著的提高代码的质量,这一点已经在很多的DSP上得到了验证.更多还原

【Abstract】 In this paper,we mainly explore the problem of code selection in code generation for embedded digital signal processor.We explore how such complex instructions affect the detection of optimal tree covering.Meanwhile,we introduce a two-phase model for code selection which can exploit available instruction parallel efficiently.Compared with previous work,this technology can significantly improve the code quality,which is demonstrated for a widespread DSPs.更多还原
